Imaging overuse in the emergency department: The view of radiologists and emergency physicians

To identify the perceived factors contributing to imaging overuse in the emergency department, according to radiologists and emergency physicians.

A survey study on imaging overuse in the emergency department was conducted among 66 radiologists and 425 emergency physicians. Five-point Likert scales (not a problem at all/strongly disagree [score 1] to very serious problem/strongly agree [score 5]) were used to score the various aspects of overimaging.

Both radiologists and emergency physicians gave a median score of 4 to the question if imaging overuse is a problem in their emergency department. CT accounts for the vast majority of imaging overuse, according to both radiologists (84.8%) and emergency physicians (75.3%). Defensive medicine/fear of malpractice, the presence of less experienced staff, and easy access to imaging all were given a median score of 4 as factors that influence imaging overuse, by both physician groups. Median ratings regarding the influence of pressure from patients and a lack of time to examine patients on imaging overuse varied between 3 and 4 for radiologists and emergency physicians. Pressure from consultants to perform imaging, the use of imaging to decrease turnaround time in the emergency department, a lack of space in the emergency department, a lack of proper medical education, and inability to access outside imaging studies, were also indicated to give rise to imaging overuse.

Imaging overuse in the emergency department (particularly CT overuse) is a problem according to most radiologists and emergency physicians, and is driven by several factors.
